Description
Technical field
The utility model is related to valve technology field, especially a kind of hard sealing membrane piece.
Background technology
With the continuous development of whole world clean energy resource, the field that solar power generation uses is more and more extensive, but the sun
The cleaning needs of monocrystalline silicon and polysilicon glass plate that power generation can be gone up are cleaned using many strong acid and strong base substance, due to this
Huge, many photovoltaics and be all annual without the production stopped in market, this just carries the valve for transmitting these strong acid and highly basic medium
Going out can higher service life requirement；
Due to needing to transmit strong acid and highly basic medium, our valve diaphragm can only use PTFE (polytetrafluoroethylene (PTFE)) this
King material can just satisfy the use demand, and be unlikely to by medium to be corroded；
The maximum service life (MSL) of the existing market country and external rubber+PTFE membrane can only be at 300,000 times or so, can only
Meet or so customer equipment operating half a year；
Conventional patch design principle both domestic and external is at present：Back side compounded rubber and PTFE, by being squeezed to caoutchouc elasticity
Pressure makes diaphragm seal, since the tensile strength of rubber is poor, after repeatedly extruding and pullling impact, often will produce cracking
Situation.
Utility model content
The technical problems to be solved in the utility model is：In order to solve existing back side compounded rubber and PTFE, by rubber
The extruding of glue elasticity makes diaphragm seal, since the tensile strength of rubber is poor, after repeatedly extruding and pullling impact, can produce
Raw cracking condition problem, the utility model provide a kind of hard sealing membrane piece, for connect with valve, including diaphragm ontology, consolidate
Determine component and connecting component, connecting component one end and this body by integral forming of diaphragm, the other end and the fixed component one of connecting component
Body formed, connecting component opens or closes valve by changing its movement travel, and the existing back side of effective solution is multiple
Rubber and PTFE are closed, by making diaphragm seal to the extruding of caoutchouc elasticity, since the tensile strength of rubber is poor, by repeatedly
After squeezing and pullling impact, cracking condition problem will produce.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of hard sealing membrane piece is used to connect with valve, including diaphragm ontology, fixed component and connecting component, the company
Relay part one end and described this body by integral forming of diaphragm, the other end of the connecting component are integrally formed with the fixed component,
The connecting component opens or closes the valve by changing its movement travel.
Specifically, connecting component is motion of membrane band, and the motion of membrane band is in arc-shaped.
Specifically, the motion of membrane strip length is 0.4mm.
Specifically, the valve includes the valve body being connect with diaphragm outer body face, is arranged in the valve inner
Piston and the trim ring that is arranged between the piston and the valve body.
Specifically, the contact surface of the diaphragm ontology and the valve body is spherical shape.
Specifically, the inner side mounting thread of the diaphragm ontology matches connection with the piston.
Specifically, the fixed component is the diaphragm outer shroud that matching is fixed between the valve body and the trim ring.
The utility model has the beneficial effects that：The utility model provides a kind of hard sealing membrane piece, for being connect with valve,
Including diaphragm ontology, fixed component and connecting component, connecting component one end and this body by integral forming of diaphragm, connecting component it is another
End is integrally formed with fixed component, and connecting component opens or closes valve by changing its movement travel, effective to solve
Determined existing back side compounded rubber and PTFE, by making diaphragm seal to the extruding of caoutchouc elasticity, due to the tensile strength of rubber
It is poor, cracking condition problem after repeatedly extruding and pullling impact, is being will produce, by using the hard sealing membrane of this spline structure
Piece improves its service life, and access times can reach 1,000,000 times or more, can meet customer equipment and be used continuously 2 years
More than.

Embodiment 1
A kind of hard sealing membrane piece is used to connect with valve 1, including diaphragm ontology 2, fixed component 3 and connecting component 4, even
4 one end of relay part is integrally formed with diaphragm ontology 2, and the other end and the fixed component 3 of connecting component 4 are integrally formed, connecting component 4
Valve 1 is opened or closed by changing its movement travel, connecting component 4 is motion of membrane band 40, motion of membrane band 40
In arc-shaped, 40 length of motion of membrane band is 0.4mm, and valve 1 includes the valve body 11 being connect with 2 lateral surface of diaphragm ontology, setting
Piston 12 inside valve body 11 and the trim ring 13 being arranged between piston 12 and valve body 11, diaphragm ontology 2 and valve body 11
